Students will be asked to create two scatter plots (one for games 1-23 and a second for games 24-46). Students will then choose appropriate regression models for the growth of advertising costs. Students will choose these models based on visual representations as well as appropriate r or r2 values. Teachers can also introduce residuals here. Teachers can also help the students graph the equations as a piecewise function so that they can see the change in growth rate. Super Teachers need to

Several High School students use the TI84 graphing calculator for their math classes. The most asked questions are always “How do I do this” and “My calculator is broken, how do I fix it?” This brief tutorial should help you with some of the basic instructions for students and teachers to get started on the calculator. Please look for other files helping with graphing, regressions and other calculator steps. 1. Resetting the Calculator 2. Changing between Radian and degree modes 3. Catalog 4. No

Several High School students use the TI84 graphing calculator for their math classes. The most asked questions are always “How do I do this” and “My calculator is broken, how do I fix it?” This brief tutorial is the second in a series. The first tutorial addressed Resetting the Calculator, Changing between Radian and degree modes, Catalog, Normal and Scientific Notation and Storing Values. This tutorial will address graphing equations and inequalities. Please look for other files helping wit

Postal rates have been figured by the ounce since July 1, 1885. Students• This activity allows the students to create graphs and equations based on the price of mailing a letter up to one ounce. The explanation of reasoning pieces are important as we move to the common core and also are more aware of the importance of English results

Some questions in algebra and algebra 2 will ask for the equation of a curve or correlation coefficient. The r-value number describes both how well the equation of the curve fits and whether the graph is increasing or decreasing. The r- value will be positive if the graph is increasing and the r-value will be negative if the graph is decreasing. The closer the absolute value of r is to 1, the better the curve fits the data. An r-value of 1 means the curve fits the data perfectly and has a positi

How much math is incorporated in theme parks? The following eleven questions are geometry review questions that are also centered around theme parks. Please answer each question, showing all work. So put on your swim suits and break out the sun screen and lets go to the theme park. Circles, logic, c More…onstructions, parabolas, arcs, volume, equations of a line and area are addressed
